9040 Classic for REA & M90 Systems - Maintenance
Equipment Required: Equipment Required: Equipment Required: Equipment Required: Equipment Required:
- Test Resistor (16688-01)
- Current Meter (76652-02)
1. Turn AC power to the power supply OFF OFF OFF OFF OFF.
2. Remove the high voltage cable from the power
supply.
3. Turn the high voltage adjust knob FULLY
counter-clockwise.
4. Connect one end of the test resistor (16688-
01) through the current meter (76652-02) to ground
as shown in Figure 8. Insert the other end of the
test resistor into the HV output tube of the
power supply.
5. Open the cabinet door and position jumper JP4
on the main PC Board so that it covers (shorts)
both terminals.
6. Turn the AC power to the power supply ON.
7. SLOWLY adjust the kV adjust knob fully
clockwise. The external current meter (76652-02)
should read within the ranges noted in Figure 7. If
it reads correctly, the problem is not in the power
supply and the high voltage cable and spray
applicator should be checked for the cause. If the
reading is not within the specified range refer to
"Bench Testing" in the "Maintenance" section of
this manual. If the external current meter reads
correctly, but the meter on the power supply does
not, replace the power supply meter.
8. Turn the power supply OFF. Disconnect the
current meter (76652-02) and remove the test
resistor (16688-01). Reposition JP4 so that it
covers only one terminal. When ready to resume
spray operations, reconnect the high voltage cable
and turn the power supply ON.

> Whenever removing high voltage cables
from equipment, ground the plug end of the
cable(s) by contacting the plug to electrical
ground. DO NOT
DO NOT DO NOT DO NOT DO NOT touch the plug until it has
been grounded. This will eliminate the
possibility of residual charge causing electri-
cal shock.
